大姚核桃春夏嫁接对比试验

Dayao Walnut Grafting Contrast Experiments in Spring and Summer

文章通过观察核桃树在春季、夏季嫁接的成活率,成活后的长势情况,选择地径基本相同的实生核桃苗25株作砧木,采用相同的嫁接方法进行春季和夏季嫁接,用相同的管理方式对嫁接后的苗木进行管理。试验结果表明,春季和夏季嫁接核桃树同样能够成活,且成活率都高,嫁接后的长势当年有所差别。在一年中,夏季嫁接可作为春季嫁接的补充。

In the contrast experiments, 25 living walnut seedlings, which yield in the fields whose diameters are same basically, are selected as stocks which are grafted by same grafting methods in spring and summer. This grafted seedlings are nursed in the same management way.By observing the survival rate of the grafting trees between the spring and summer, and the growing situation after the survival, the results show that the grafting trees can both survive in spring and summer with super survival rate, but its grafting situation is quite different. During a year, the summer grafting can be used to supplement the spring grafting.
